Convex Lens Lab

Abstract: In this lab we measured various figure of speech and design keeps that produced different pick up heights. We did so victimization deuce different lenses, unity with a focal distance of +200mm, and one with a focal length of + speed of lightmm. Both setups include a light source at one bar of an visual bench and a screen at the other. In some(prenominal) trials, we found that as distance of the object increases, the distance of the cooking stove becomes closer to the focal length of the lens. We besides found that the hyperbole of each lens increases in a linear pattern. intention: In order to understand this lab, one must devolve on in the lens compare. This equation is 1/f= 1/do+ 1/di. In this, f is focal length, do is the distance from the object to the lens, and di is the distance from the lens to the image. Magnification is also important. The magnification, or the change in size from the original object to the produced image, apprize be found b y using the equation hi/ho= di/do. In this hi is the height of the image, small-arm ho is the height of the object. A diagram of these situations can be seen below. data-based/Discussion: We first used the +200mm lens and pose it on the optics bench, in between the light source and the screen. We locomote the lens forward and back so that various size images were produced on the screen. We conducted the same procedure a second while simply instead used a +100mm lens. The data pile up for both trials can be seen below. +200mm do (cm)di (cm)hi (cm)ho (cm)hi/ho (cm)do/di(cm) 81.227.3250.40.336206897 26.5821352.63.094339623 62.530.52.550.50.488 3063951.82.1 37.243.35511.163978495 8426.71.550.30.317857143 286110.552.12.178571429 25.687.914.352.863.43359375 40.639.9450.80.982758621 33.5526.551.31.552238806 +100 do(cm)di(cm)hi(cm)ho(cm)hi/ho(cm)di/do(cm) 125218.553.74.333333333 14.331.79.551.92.216783217 17.522.25511.268571429 22.517.83.550.70.79111111 1 13.534.510.552.1...If you hope to get a ! full essay, order it on our website: OrderCustomPaper.com
